TRAP-OPERATING MEANS.

Application illed February 26, 1910, Serial No. 546,110. v Renewed May24, 1911.y Serial No. 629,447.

To all 'whom t may concern Be it known that I, CHARLES DAVID TILLI- soN,a citizen of the .United States, residing atOakl-and, in the county ofAlameda and State of California, have invented certain new and usefulImprovementsl in Trap- Operating Means, of which the following is aspecification.

This invention relates to steam, vacuum, or like traps wherein a quickacting air valveis employed, and the principal object of the same is toprovide the trap with means whereby the air valve will be automaticallyand quicklyand suddenly opened when the usual float in the tank rises.

In carrying out the* objects of the invention generally stated above itwill be understood, of course, that the essential features thereof arenecessarily susceptible of changes in details and structuralarrangements, one preferred and practical embodiment of which is shownin the accompanying drawings, wherein Figure 1 is a view in sideelevation of the improved trap, the air valve being closed. Fig. 2 is asimilar view, the air valve being opened. Fig. 3 is a detail top planview of the stuffing box for the trap. Fig. 4 is a fragmentary verticalsectional view taken on the line A--A, Fig. 2.

This invention is primarily intended as an improvement on my Patent' No.948,028 granted February 1, 1910, and embodies novel means which assuresquick action in the opening and closing of the air valve and alsoprovides means for holding the valve open when the float is up andholding the valve closed when the float is down.

Referring to said drawings by numerals, 1 designates the tra-p; 2 thecover thereof; 3 the bonnet that projects from one end ofthe trap andinto which one end of the air supply` pipe 4 projects. The clamp 5 thatembraces the free upper portion of said pipe, is equipped with anupright supporting arm 6 which has the rocking lever 7 pivoted thereto,the outer end of which is provided with a weight. A valve 8 is suspendedfrom said lever 7 and is adapted to be seated on the outer end of pipe 4to seal the same. A stuiiing box 9 is mounted in bonnet 3 and carries arocker shaft 10 that is connected with a float in trap 1. Said shaft 10has one4 of its projected ends equipped witha crank 11 that is ivotallyconnected to the lower end of a link 12, The structure described issubratentec ont. 31,' 1911.-y

stantially the same as that covered by my' A Patent948,028 and is usedas anv example of a trap to which the improved valve loperating meansmaybe applied.

The upper end of link 12 is suitably attached tothe base of a yoke 13whose upright arms are' provided with'a longitudinalA eoy slot 14 whichslidably receives the ends ofy a pivot bolt 15 that connects a pair ofparah 19 of lever 7. An upper abutment 2O and a lower abutment 21 arecarried bythe upper portion of rod 1,8, said abutments beingsuit-`rablyspaced to compensate for lost mot-ion of said rod, and are adaptedtol elevate or depress lever 7 according to the movement of rod 18.

The forward ends of link bars 16 project through and beyond yoke 13 andare pivotally connected to one end of-a link bar 22 which has itsotherend pivotally connected to the outer end of a link 23 that projectsfrom a pivot ear 24 carried by the top 2 of trap 1. The link bars 16,adjacent their connection with clamp lug 17, are each provided with anoutwardly projecting lateral lug 25 and link bar 22 adjacent itsconnection with link 23 isprovided with lateral lugs 26. Lugs 25-26 areconnected by spiral springs 27.

In operation, an upward movement of the float in the tank will causelink 12 to raise yoke 13. On its initial movement the slotted Pivot bolt15 repast the pivotal connection of bars ,22 and l 16 being projectedupward automatically by the tension of springs 27 so that valve 8 issuddenly removed from pipe 4. On the down stroke of the lloat, valve 8is similarly forced toits seatson pipe 4. As will be understood, thespring connection between bars 16 and 22 constantly exerts a tension todraw the outer end of said bars together, thereby producing means'.which prevents said bars lbeing accidentally operated in e. manner thatwould affect the valve 8.

What claim as my invention is 1. A devicer of the character describedcomprising a trap, a supply pipe therefor, a Valve controlling 'saidpipe, a link operated by a means Within said trap, a rod having a looseyoke connection with said link, means engaging said rod for operatingsaid valve, a toggle having a pivotal connection with said pipe and saidtrap and also connected to said rod, and springs carried by said togglefor causing the same to accelerate the operation of said rod.

2. A device of `the character described comprising a yoke, a crank armsecured to a rocker shaft Within a stuiling box in the supply pipe of atrap, means Within said trap for operating said rocker shaft, and a rodconnecting said crank arm to said yoke, said yoke provided With sideslots, a pivot bolt slidable in said slots, a valve operating rod havingone end mounted on' said bolt, a

' toggle also connected to said bolt, and means for causing'saidvtoggleto automatically accelerate the operation of said rod.

3; A device( of the character described comprising'a trap, a supplypipe, a valve mechanism mounted upon said pipe, a rod pivotally mountedon said pipe, and terminating in a yoke, a second rod mounted upon 3cSaid valve mechanism, a pin slidably con- Loomis nesting said rod tosaid yoke, a pair of toggle arms pivotally mounted upon said pin, oneend of said arms attached to said supply pipe, the free end 0i said armspivotally mounted upon a supporting link upon said i trap, springsmounted upon said arms, and a tioat within said trap for operating saidroc s.

s. A device of the character described comprising a trap, a supply pipeconnected thereto, valve mechanism mounted upon said pipe, a rodpivotally connected to said supply pipe, one end ofsaid rod providedwith a yoke, a second rod, one end of said. rod slidably connected tosaid valve mechanism, the other end slidably mounted Within said yoke, apair of toggle arms connected to said rods, means forV supporting theends of said toggle arms, a lugextending from each end of said togglearms, a plurality of coil springs attached to said lugs to hold saidarms in position to retain said valve either open or closed, and meansWithin said trap for operating said mechanism. t
